SEO for drainage engineers: be the first call for a blocked drain

How does a drainage company get more calls from Google? For emergencies such as “blocked drain near me”, it is mostly the map pack, so a rule-safe Google Business Profile, steady reviews and a fast mobile site come first. For planned work, such as CCTV drain surveys for house buyers and drain relining, clear service pages that answer people’s questions win the enquiries. Unavoidable Marketing is a Leeds-based agency that does SEO and local SEO for UK drainage engineers, and founder Andrew Heppinstall is on every strategy call.

Two kinds of drainage customer

Drainage work splits cleanly in two, and your SEO should treat them differently.

Winning the map pack for “blocked drain near me”

For emergency searches, the three businesses shown with the map take a large share of the calls. Getting into that pack depends on how close you are to the person searching, how relevant your profile is and how much Google trusts you. You cannot change the first, so work on the other two.

Google Business Profile rules

Drainage is a trade with plenty of lead-generation listings and fake addresses, so play it straight. Use a real address where you or your staff actually work. If customers do not come to you, which is normal for drainage, set up as a service-area business and hide the address. A virtual office or mailbox address breaks Google’s guidelines and can get the listing suspended, taking your reviews with it.

• Use your real business name, with no “24/7 Blocked Drains” added to it
• Pick the primary category that best describes your main work, and add secondary ones only for services you really offer
• Set a service area you can actually reach quickly, not the whole region
• Set honest hours. If you take calls overnight, say so. If not, do not claim 24 hours
• Add photos of your vans, jetting kit and camera equipment, and real jobs

Reviews, steadily

Ask every customer for a review before you leave site, ideally with a text containing the link so they can do it there and then. Ask them to mention the job and the area, such as “cleared a blocked drain under the patio in Rothwell within the hour”. Reply to every review by name. Recent, detailed reviews are one of the few things lead-generation listings cannot fake well.

A fast mobile site for people in a panic

Most emergency drainage visits come from phones, often on poor signal. If the page takes ages to load or the number is hard to find, they go back and tap the next result.

• A tap-to-call button visible straight away on every page
• Pages that load quickly on mobile data, with images compressed
• Your areas covered and typical response near the top
• No pop-ups covering the phone number
• Clear, honest information on call-out charges and how you price, without hiding anything

Emergency pages that are worth ranking

Give each common emergency its own page: blocked drains, blocked toilets, blocked sinks, overflowing manholes, and drain smells. Each should say what you do when you arrive, such as rodding or high-pressure jetting, what the customer can safely check first, and what to do while they wait. Short, practical, calm. A page that tells someone not to keep flushing earns trust, even if they end up ringing someone else this time.

CCTV survey pages, including homebuyer surveys

CCTV drain surveys are planned work with real search demand, and much of it comes from house buyers. Their surveyor or mortgage lender suggests a drain survey, and they have no idea what one involves. A clear page wins those enquiries:

• What a CCTV drain survey is and what the camera shows
• When buyers should get one, such as older properties, large trees near the drain run or signs of past problems
• What the report includes, with a sample page if you can share one
• How quickly you can survey and send the report, because buyers are working to deadlines
• What happens if the survey finds a defect, and how it can be used in price negotiations

Separate pages for landlords and commercial clients, such as restaurants with grease problems, are worth adding if you want that work.

Relining and repair content

When a survey finds a cracked pipe or root ingress, customers want to know their options. Explain drain relining in plain English: what it is, when it suits and when excavation is the better answer. Cover patch repairs, root cutting and full replacement. Use your own camera footage stills from before and after. Customers facing a repair bill trust the company that explains the options fairly.

Who is responsible for which drain?

This is one of the most searched drainage questions, and a clear general answer brings in a lot of traffic. In broad terms, homeowners are usually responsible for drains that serve only their property and sit within its boundary. Pipes shared with neighbours, or that run beyond the boundary, are often the responsibility of the local water company. The exact position depends on the property and the part of the UK, so tell people to check with their water company if they are unsure, and explain what you can check for them. Do not give firm legal answers, but a calm explainer from a working engineer is exactly what people want to read.

Answer-first pages like this are also what AI assistants such as ChatGPT and Google AI Overviews draw on. Consistent business details, reviews, mentions on trusted sites and structured data help too, though nobody can guarantee being named.
